I've been from Whitewell up to the Beanaidh Beag turnoff (for N.side of Braeriach). It's rough and stony in places but very bikeable thus far: I can't speak for those last few km up to Loch Einich. I had a decent bike but i'm not a decent MTB-er by any stretch, so I'm sure you'd be fine - if a bit jarred on the descent.
Just read your post, I would like to point out that sometimes the burn/stream that is after metal bridge(past halfway up) is hard to pass without getting very wet feet. I have cycled up Glen Einich numerous times only to come to this natural obstacle and had to turn back due to high water. It may well be up to knee deep if there has been heavy rain or snowmelt.
It's well worth pushing on though if possible till you reach the loch at the end, as it's a great backdrop with the cliffs of Sgor Gaoith behind the Loch.
